In a medium pot combine 6 cups of water, the juice of 2 lemons, 1 lemon sliced, 2 tablespoons grated ginger, 2 tablespoons sliced ginger, and 1 teaspoon turmeric powder.

Place the pot over medium-high heat and bring the mixture to a gentle boil. Once boiling, reduce the heat to low and simmer for 3–5 minutes to infuse the flavors.

Remove the pot from the heat and let it sit 1–2 minutes to cool slightly.

Strain the liquid through a fine-mesh strainer into a heatproof pitcher or bowl, pressing the solids lightly to extract the liquid. Discard the solids left in the strainer.

While the liquid is warm, stir in honey, starting with 1/2 cup. Taste and add more honey up to a total of 3/4 cup if you prefer it sweeter.

Pour the sweetened drink into serving glasses. If using the optional 2/3 cup pomegranate arils, divide them among the glasses (they will sink to the bottom). Garnish each glass with optional lemon slices, if desired.

Serve hot.

To store, let any leftover drink cool to room temperature, transfer to an airtight container, and refrigerate for up to 5 days. Reheat the amount you need before serving.
